The patent basically incorporates the same features and sensors of the current trackpad design, but instead does away with the hinge that allows to be clickable. Instead an actuator will be used to provide tactile feedback which could also be adjusted in the settings, where users will be able to adjust the sensitivity levels for the click pressure of the tactile feedback. We’re not sure what the point is for a buttonless trackpad. Perhaps less moving parts could also mean a slightly thinner design, but at the same time there are plenty of users out there who still require the familiar clicking feedback. However given that the patent is four years old, it would seem that it was an old idea that might never see the light of day.
